What is Random String Generator?
This generator uses the browser's crypto.getRandomValues API to assemble strings from a configurable alphabet of lowercase letters, uppercase letters, digits, and symbols. Use it for sample data, ad-hoc IDs, request tokens, or anywhere you need a quick high-entropy filler. If you do not pick any character class, it falls back to letters and digits so you always get a usable result.

FAQ
- How is this different from the password generator?
- This tool is tuned for generic strings — placeholder data, lookup keys, sample IDs. The password tool enforces one character from every selected class.
- Is the randomness suitable for security?
- It uses the same crypto.getRandomValues source as the password tool, which is suitable for tokens. For true cryptographic keys, derive them in your own application code instead.
